S4 Rad into S5??
 

can you use S4 radiator in S5 N/A 13b. looks like it could be done. Anyone done it? how hard and what else do you need besides a S4 Radiator?

difference is where the cap sits - s5 rad has 3 necks, s4 rad has 2 necks, with cap sitting by alternator i think.

it might be hard to bleed as the filler cap will be lower...
